Abstract:
Climatic change is widely acknowledged to have played a role in the dispersal of modern humans out of<br/>
Africa, but the timing is contentious. Genetic evidence links dispersal to climatic change ~60,000 years<br/>
ago, despite increasing evidence for earlier modern human presence in Asia. We report a deep seismic<br/>
and near-continuous core record of the last 150,000 years from Lake Tana, Ethiopia, close to early<br/>
modern human fossil sites and to postulated dispersal routes. The record shows varied climate towards<br/>
the end of the penultimate glacial, followed by an abrupt change to relatively stable moist climate<br/>
during the last interglacial. These conditions could have favoured selection for behavioural versatility,<br/>
population growth and range expansion, supporting models of early, multiple dispersals of modern<br/>
humans from Africa.
